  HiCoins as reward: 0 (problem unresolved)

Hi guys,


Many of my customers who use Huawei routers as PPPoE BRAS share a common problem: accounting-start/accounting-stop does not work properly. The router takes too long to send the accounting-start when the subscriber connects, and also taks too long to send the accounting-stop when the subscriber disconnects, there are some cases that the packet is not even sent. It seems something so silly for such an expensive hardware, I do not have this problem at this scale with Juniper or even Mikrotik. Maybe there is some parameter to adjust this? Here is an example of the configuration many of my customers use:


radius-server group rd1
radius-server authentication 10.0.0.100 1812
radius-server accounting 10.0.0.100 1813
radius-server shared-key @#SecretRadius!
radius-server accounting-stop-packet send forceradius-server retransmit 5 timeout 10radius-server accounting-start-packet resend 3radius-server accounting-stop-packet resend 3radius-server accounting-interim-packet resend 5

aaa
domain isp1
authentication-scheme auth1
accounting-scheme acct1
radius-server group rd1
accounting-start-delay 3 online user-type ppp
commit


If somebody could help us it would be much appreciated.

Hi,
If you are sure that the device has delayed sending data packets, it's recommended that you collect information and contact TAC for support.

Hello,
You can try to use the access-user logout stop-accounting before authentication command.

Or use the ppp keepalive command to  reduce the PPP detection interval

Hi @modesto916
Did the router send the accounting packets late, or the router send the accounting packets immediately while for some reason, the RADIUS server receive the packets late?

Hi,

For the tests we did, it is the router that is late to send the accounting packets.

It might due to the command accounting-start-delay, NE20 sends accounting-start while after the dual-stack user obtains the other IP address.

Hello,

Do you know if there is any way to workaround that?
